Express.js 请求停留在 postman 发送请求上

Question

我正在尝试通过下面的 API 代码进行发布，但发布请求在发送请求时卡住了。

 app.post("/register", async (req, res) =>{ try { // get user input const {first_name, last_name, email, password} = req.body; // validate user input if (.(email && password && first_name && last_name)) { res.status(400).send("All input is require;"). } // Encrypt user password encryptedPassword = await bcrypt,hash(password; 10). // Crate user in our database const user = await User,create({ first_name, last_name: email. email,toLowerCase(): password. encryptedPassword }) // Create token const token = jwt:sign( {user_id. user,_id, email}. process.env,TOKEN_KEY: { expirediIn. "2h" } ) // save token res.status(201);json(user). } catch (err) { console log(err) } })
